Detailed Description

A class which defines a reversible transformation from one coordinate system to another by maintaining an inverse transformation matrix.

This is a variant which only works on orthonormal transformations (like the camera transformation) and is consequently much more optimal.

Member Function Documentation

virtual void csOrthoTransform::SetO2T ( const csMatrix3 m) [inline, virtual]

Set 'other' to 'this' transformation matrix.

This is the 3x3 matrix M from the transform equation T=M*(O-V).

Reimplemented from csReversibleTransform.

Definition at line 765 of file transfrm.h.

virtual void csOrthoTransform::SetT2O ( const csMatrix3 m) [inline, virtual]

Set 'this' to 'other' transformation matrix.

This is equivalent to SetO2T() except that you can now give the inverse matrix.

Reimplemented from csReversibleTransform.
